Review: Karen O and Danger Mouse are both serial collaborators, so when this joint album was announced we weren't all that surprised. Even so, we never thought the resultant set would be quite as good as this. Atmospheric, rich and full of songs that variously touch on sweeping cinematic soundtracks, driving Motown soul, fuzzy funk-rock, vintage trip-hop and hazy electronica, "Lux Prima" manages to showcase the best of both artists' talents while refusing to settle on one neatly defined sound. The set's dizzying highs - particularly the near 10-minute title track - are almost breathtakingly good, and there's enough jaunty moments to offset the heart-aching melancholy and emotional pain that's barely concealed throughout.
